Kodama of the East Tree

Petrified Field

Echoing Deeps

Horizon Explorer

Dancing from Dark to Dawn

How it works

1. Play Petrified Field.
2. When Petrified Field enters the battlefield, Kodama of the East Tree and Dancing from Dark to Dawn trigger.
3. Resolve the Kodama of the East Tree trigger, putting nothing onto the battlefield.
4. Holding priority, activate Petrified Field's second ability by tapping and sacrificing it, returning Echoing Deeps from your graveyard to your hand.
5. Resolve the Dancing from Dark to Dawn trigger, creating a token.
6. When the token enters the battlefield, Kodama of the East Tree triggers, putting Echoing Deeps from your hand onto the battlefield untapped as a copy of Petrified Field.
7. When Echoing Deeps enters the battlefield, Dancing from Dark to Dawn triggers.
8. Holding priority, activate Echoing Deeps using Petrified Field's second ability by tapping and sacrificing it, returning Petrified Field from your graveyard to your hand.
9. Resolve the Dancing from Dark to Dawn trigger, creating a token.
10. When the token enters the battlefield, Kodama of the East Tree triggers, putting Petrified Field from your hand onto the battlefield.
11. When Petrified Field enters the battlefield, Dancing from Dark to Dawn triggers.
12. Repeat from step 4.

This ingenious loop relies on a clever dance between land drops and token generation, anchored by Kodama of the East Tree and Dancing from Dark to Dawn to continually turn entries into fresh triggers. As you alternate playing Petrified Field and its graveyard-copying successor Echoing Deeps, their respective sacrifices fuel each other's return to your hand while a steady stream of Bear tokens keeps Kodama triggering endlessly. Meanwhile, Horizon Explorer ensures every single land drops straight into play untapped to keep the momentum going without skipping a beat.
